BACKGROUND: The use of antimicrobial drugs in the treatment of gonorrhea began in 1930 with the use of sulfonamides. Through the years, other drugs such as penicillin, spectinomycin, tetracycline among others, came into use. Although highly efficient at first, with the passing of time these drugs began to present untoward therapeutic results, because of the appearance of cases with chromosomic and plasmidial resistance. Because of this, in order to establish a program to combat and control a determined bacterial morbidity, it was necessary to carry out a program of epidemiologic surveillance evaluating the sensitivity behavior of the etiologic agents against the various therapeutic agents. OBJECTIVES AND METHODS: The objective of this work was to evaluate the susceptibility of strains of Neisseria gonorrhoeae to the five drugs which are mostly used for the treatment of gonorrhea in Brazil (pencillin; cefoxitine; tetracycline; thiamphenicol and spectinomycine), by Minimum Inhibitory Concentration. RESULTS AND CONCLUSION: We concluded that drugs such as cefoxitine, thiamphenicol and spectinomycine are still excellent drugs for the treatment of gonorrhea. Although penicillin continues to be effective, its use requires greater care, due to the emergence of resistant strains, and tetracycline must be absolutely avoided for the treatment of gonorrhea.
